The invention discloses a methanol fuel leakproof device for a marine methanol engine, which is characterized in that the output end of a methanol storage tank is sequentially connected with a methanol delivery pump, a methanol filter and an inner pipe at one end of a methanol double-wall pipe, the inner pipe is in bypass connection with methanol ejectors of cylinders of the marine methanol engine respectively, and the inner pipe at the other end of the methanol double-wall pipe is connected with the methanol storage tank. An outer pipe of the methanol double-wall pipe is connected with the upper part of the heating water tank through a water feeding pipe, and one end of a water discharging pipe is connected with the lower part of the heating water tank and then bypasses the outer pipe of the methanol double-wall pipe through a gear pump and an isolation water filter in sequence. A detection pipe of the methanol monitor extends into the upper end of the heating water tank, and the methanol monitor is electrically connected with the machine belt alarm device and the PLC through signal lines. The marine methanol engine is compact in structure, multiple protection measures are adopted, and operation safety of the marine methanol engine is guaranteed.
